Human Apoptotic Array revealed an increased expression of five apoptotic proteins BIM, CD40, IGFBP2, P21, and SMAC, following sera incubation of non-chronic pediatric ITP patients, compared to chronic patients' sera, at diagnosis.
Our data contribute to knowledge on apoptosis markers that may aid in predicting the prognosis of children with ITP.
The key message of our article is that children with chronic ITP have a different apoptotic profile compared to non-chronic ITP. Addition to existing literature This is the first study comparing apoptotic markers between children with chronic ITP to non-chronic ITP.
Our findings indicate that, in the future, apoptotic markers may help to classify ITP patients into non-chronic versus chronic ones, at diagnosis.

We aimed to establish reference values of rSOfor preterm infants during the first week after birth, both crude and modeled based on predictors.
We included infants with gestational age (GA) &lt;32 weeks and/or birth weight &lt;1200?g. We excluded infants who developed necrotizing enterocolitis or sepsis or who died. In the first week after birth, we determined a daily 2-h mean of rSOto assess its associations with sex, GA, postnatal age (PNA), small-for-gestational age (SGA) status, patent ductus arteriosus, hemoglobin, nutrition, and head circumference at birth and translated those into a prediction model.
We included 220 infants. On day 1, the mean?±?SD rSOvalue was 48.2%?±?16.6. The nadir of rSOwas on day 4 (38.7%?±?16.6 smoothed line) to 5 (37.4%±17.3, actual data), after which rSOincreased to 44.2%?±?16.6 on day 7. The final model otional age and in small-for-gestational age infants. Regional splanchnic oxygen saturation decreases with a higher postnatal age until day 4 after birth and then increases until day 7 after birth. Gestational age, postnatal age, and small-for-gestational age status affect regional splanchnic oxygen saturation and need to be taken into account when interpreting regional splanchnic oxygen saturations using NIRS. Reference values for infant regional splanchnic oxygen saturation can be computed with a formula based on these variables, as provided by this study.The aims of this study were to find the normal value of fronto-temporal horn ratio (FTHR) as a marker of ventriculomegaly on cranial ultrasound (CUS) in premature newborns and the relation to white matter injury (WMI) and cerebral palsy (CP).
This is a retrospective study of newborns admitted between 2011 and 2014. Inclusion criteria were (1) gestation &lt;29 weeks, (2) birth weight ?1500?g, (3) referred within 7 days of life, (4) at least two CUS preformed, (5) brain magnetic resonance imaging (MRI) at term age-equivalent. Intraventricular hemorrhage (IVH) grade was identified and FTHR was measured on all CUS. WMI on MRI was evaluated through (1) injury score (Kidokoro 2013) and (2) fractional anisotropy (FA) on the MRI diffusion tensor imaging. CP was estimated using the gross motor function classification system (GMFCS).
One hundred neonates met the inclusion criteria 37 with no IVH, 36 with IVH grade 1-2, and 27 with IVH grade 3-4. The FTHR cut-point of 0.51 had the highest sensitivity and specificity for moderate-to-severe WMI. In the IVH grade 3-4 group, the elevated FTHR correlated with lower FA and higher GMFCS.
FTHR is a useful quantitative biomarker of ventriculomegaly in preterm newborns. It may help standardize ventricular measurement and direct intervention.
The fronto-temporal horn ratio has the potential to become a standardized tool that can provide an actionable measure to direct intervention for post-hemorrhagic ventricular dilation. This current study will provide the basis of a future clinical trial to optimize intervention timing to decrease the risk of white matter injury in this vulnerable population.

Eleven anesthetized preterm fetal lambs (gestation 128?±?2 days) were instrumented with (1) an LV micromanometer-conductance catheter to obtain LV end-diastolic volume (EDV) and end-diastolic pressure (EDP), the maximal rate of rise of LV pressure (dP/dt), LV output, LV stroke work, and LV end-systolic elastance (E), a relatively load-independent measure of contractility; (2) an endotracheal tube to measure mean tracheal pressure and to reduce lung liquid volume. LV transmural pressure was calculated as LV EDP minus tracheal pressure.
Reducing lung liquid volume by 16 ± 4?ml?kg(1) augmented LV output (by 16%, P?=?0.001) and stroke work (29%, P?&lt;?0.001), (2) increased LV EDV (12%, P?&lt;?0.001), (3) increased LV transmural pressure (2.2?mmHg, P?&lt;?0.001), (4) did not change LV dP/dtliquid filling the fetal lungs lessens the degree of external constraint on the heart. This lesser constraint permits a rise in left ventricular dimensions and thus greater cardiac filling that leads to increased left ventricular pumping performance. This study has defined a mechanism whereby a reduction in lung liquid volume results in enhanced pumping performance of the fetal heart. These findings suggest that a reduction in lung liquid volume which occurs during the birth transition contributes to increases in left ventricular dimensions and pumping performance known to occur with birth.
